Inheritance diagram for uhd::usrp::dboard_iface:

## Detailed Description

The daughter board dboard interface to be subclassed. A dboard instance interfaces with the mboard though this api. This interface provides i2c, spi, gpio, atr, aux dac/adc access. Each mboard should have a specially tailored iface for its dboard.
